This application claims priority to Chinese Patent Application No. 202322927980.7, filed on October 30, 2023, Chinese Patent Application No. 202322945047.2, filed on October 31, 2023, and Chinese Patent Application No. 202311438283.3, filed on October 31, 2023, the entire contents of which are incorporated herein by reference.

The present application relates to the technical field of air conditioners, and particularly to a mounting bracket assembly and an air conditioner.

In the related art, split-type air conditioners that facilitate user self-installation use flexible refrigerant pipes to connect an indoor-side heat exchanger of an indoor unit and an outdoor-side heat exchanger of an outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor unit and the outdoor unit separately, without assembling refrigerant pipes and adding refrigerant, thereby reducing installation difficulty and enabling user self-installation.

The present application proposes a mounting bracket assembly for mounting an outdoor unit of an air conditioner. Specifically, the air conditioner of the present application can be a split-type air conditioner that facilitates user self-installation, which uses flexible refrigerant pipes to connect an indoor-side heat exchanger of an indoor unit and an outdoor-side heat exchanger of an outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor unit and the outdoor unit separately, without assembling refrigerant pipes and adding refrigerant, thereby reducing installation difficulty and enabling user self-installation. However, the present design is not limited to this. In other embodiments, the air conditioner of the present application can also be a conventional split-type air conditioner, or an integrated air conditioner, such as a window-type air conditioner. In this case, the outdoor unit refers to the portion of the window-type air conditioner that extends to the outdoor side.

The present application proposes a mounting bracket assembly. Referring to FIG. 1 to FIG. 8, in an embodiment of the present application, the mounting bracket assembly includes a mounting bracket 101 and a first bracket 20.

The mounting bracket 101 includes a main bracket 10, the main bracket 10 includes a window-mounting bracket 11 and a load-bearing bracket 12 connected to each other, the window-mounting bracket 11 is mounted on a window frame, the load-bearing bracket 12 extends along a first direction to the outside of a window 103, and an outdoor unit 102 is provided on an upper surface of the load-bearing bracket 12.

The first bracket 20 is connected to the outdoor unit 102, one of the load-bearing bracket 12 and the first bracket 20 is provided with a first limiting portion 13 capable of elastic deformation, and the other of the load-bearing bracket 12 and the first bracket 20 is provided with a second limiting portion 21, and when the outdoor unit 102 moves along the first direction on the load-bearing bracket 12, the first limiting portion 13 is capable of engaging with the second limiting portion 21.

Specifically, in the embodiment of the present application, the inner side of the window 103 is defined as the rear, and the outer side of the window 103 is defined as the front. Thus, the front-rear direction is the first direction, the upper side of the outdoor unit 102 is the upper side, and the lower side of the outdoor unit 102 is the lower side. In an embodiment, the outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 close to the window, and then pushed forward to a fixed position. That is, after being pushed in a direction away from the window to the fixed position, the first limiting portion 13 engages with the second limiting portion 21.

In other embodiments, the outdoor unit 102 can also be first placed from top to bottom on the end of the load-bearing bracket 12 away from the window, and then pulled backward to a fixed position. That is, after being pulled in a direction close to the window to the fixed position, the first limiting portion 13 engages with the second limiting portion 21.

In the technical solution of the present application, the outdoor unit 102 is first placed on the load-bearing bracket 12, and then the outdoor unit 102 is pushed or pulled along the first direction, so that the first limiting portion 13 can engage with the second limiting portion 21, thereby relatively fixing the outdoor unit 102 on the load-bearing bracket 12, i.e., completing the installation and fixation of the outdoor unit 102. In this way, through the cooperative structure of the first limiting portion 13 and the second limiting portion 21, the installation and fixation of the outdoor unit 102 do not require screws and corresponding tools such as screwdrivers. This operation is more convenient, thereby improving the user experience.

Referring to FIG. 5 to FIG. 8, in some embodiments, a lower surface of the first bracket 20 is provided with a first through-slot 22 extending along the first direction. When the outdoor unit 102 is placed on the load-bearing bracket 12 from top to bottom, the first bracket 20 is sleeved on an upper side of the load-bearing bracket 12 through the first through-slot 22. The load-bearing bracket 12 is movable within the first through-slot 22. The second limiting portion 21 is disposed in the first through-slot 22, and the first limiting portion 13 is provided on the load-bearing bracket 12. In this way, through the cooperation of the first through-slot 22 and the load-bearing bracket 12, it is beneficial for the outdoor unit 102 to move more smoothly along the first direction on the load-bearing bracket 12, and enables the first engaging protrusion 131 to engage with or disengage from the second limiting portion 21 more smoothly. In other embodiments, the second limiting portion 21 can also be provided on the load-bearing bracket 12, and the first limiting portion 13 can be disposed in the first through-slot 22. In other embodiments, the first through-slot 22 may also be omitted.

Referring to FIG. 5 to FIG. 7, in some embodiments, the load-bearing bracket 12 is provided with a first mounting groove 121 and a first through-hole 122 communicating with the first mounting groove 121. The first limiting portion 13 is disposed in the first mounting groove 121 and is provided with a first engaging protrusion 131 corresponding to the first through-hole 122. A portion of the first engaging protrusion 131 protruding out of the first through-hole 122 is capable of engaging with the second limiting portion 21. In this way, the first limiting portion 13 can elastically deform within the first mounting groove 121, and the first through-hole 122 can limit and guide the first engaging protrusion 131, thereby enabling the first engaging protrusion 131 to engage with or disengage from the second limiting portion 21 more smoothly. Of course, in other embodiments, the first mounting groove 121 and the first through-hole 122 may also be omitted, and the first limiting portion 13 can be directly formed on a side wall of the load-bearing bracket 12.

In some embodiments, the second limiting portion 21 is provided on a first side wall of the first through-slot 22, a slot opening of the first mounting groove 121 is provided on a lower surface of the load-bearing bracket 12, and the first through-hole 122 is provided on the first side wall of the first mounting groove 121. In this way, the lateral space of the load-bearing bracket 12 can be utilized to provide an operating space for the user to press the first engaging protrusion 131, facilitating the user to manually release the engagement between the first engaging protrusion 131 and the second limiting portion 21, thereby achieving the purpose of disassembling the outdoor unit 102 from the load-bearing bracket 12. Of course, in other embodiments, the second limiting portion 21 can also be provided on a bottom wall of the first through-slot 22.

Referring to FIG. 5 to FIG. 7, in some embodiments, a guide portion 23 is further provided on the first side wall of the first through-slot 22. Along the first direction and in a direction away from the window-mounting bracket 11, the second limiting portion 21 and the guide portion 23 are sequentially distributed, and the guide portion 23 extends obliquely in a direction away from the load-bearing bracket 12. Specifically, in the present application, when the outdoor unit 102 is placed on the load-bearing bracket 12 and pushed backward for fixation, during this pushing process, the first engaging protrusion 131 contacts and is acted upon by the guide portion 23, which urges the first limiting portion 13 to elastically deform and causes the first engaging protrusion 131 to automatically retract. Finally, after the first engaging protrusion 131 aligns with the second limiting portion 21, it automatically pops out and engages with the second limiting portion 21. In this way, through the guiding action of the guide portion 23, the first engaging protrusion 131 can engage with the second limiting portion 21 more smoothly. Of course, in other embodiments, the guide portion 23 may also be omitted. It can be understood that in an embodiment where the outdoor unit 102 is placed on the load-bearing bracket 12 and pulled inward for fixation, the guide portion 23 extends obliquely in a direction away from the load-bearing bracket 12 in a direction close to the window-mounting bracket 11.

It should be noted that in the embodiments of the present application, the relative positional relationship between different components defaults to the state after the outdoor unit 102 is installed in place on the main bracket 10. Special circumstances will be specifically explained.

Referring to FIG. 5, in some embodiments, the first limiting portion 13 includes two first segments 132 and two second segments 133. The two first segments 132 are opposite to each other and spaced apart from each other, and are connected by the two second segments 133. The two second segments 133 are opposite to each other and intersect each other. One of the first segments 132 is provided with the first engaging protrusion 131 and elastically abuts against one side wall of the first mounting groove 121, and the other first segment 132 elastically abuts against the other side wall of the first mounting groove 121. In this way, the first limiting portion 13 has a simple structure and is easy to implement, and can stably elastically deform within the first mounting groove 121 to provide a good driving action for the first engaging protrusion 131. Of course, in other embodiments, the first limiting portion 13 can also be directly formed on a side wall of the first mounting groove 121.

Referring to FIG. 5 to FIG. 7, in some embodiments, a bottom wall of the first mounting groove 121 is provided with a mounting through-hole 123, and the first through-slot 22 is provided with a stop portion 24 corresponding to the mounting through-hole 123. The stop portion 24 is capable of passing through the mounting through-hole 123 following the placement of the outdoor unit 102, and is capable of moving along the first direction following the outdoor unit 102 to be limitingly connected with a hole edge of the mounting through-hole 123. In this way, through the cooperation of the stop portion 24 and the mounting through-hole 123, the load-bearing bracket can further restrict the first bracket, thereby improving the installation reliability of the outdoor unit.

In an embodiment, the mounting through-hole 123 includes a clearance hole section 123a and a limiting hole section 123b that communicate with each other. The clearance hole section 123a is provided on a side of the limiting hole section close to the window-mounting bracket 11. In a width direction of the first through-slot 22, a width of the limiting hole section 123b is smaller than a width of the clearance hole section 123a. After the stop portion 24 passes through the clearance hole section 123a from top to bottom, the stop portion 24 is capable of moving along a direction away from the window-mounting bracket 11 to below the limiting hole section 123b, and abutting against a lower side surface of a hole edge of the limiting hole section 123b. In this way, the vertical restriction of the outdoor unit 102 can be quickly and easily achieved, thereby facilitating the user to install and disassemble the outdoor unit 102.

Referring to FIG. 5 to FIG. 7, in an embodiment, the first through-slot 22 includes two opposite first plate segments 224, two second plate segments 225, two opposite third plate segments 226, and a fourth plate segment 227 connecting the two third plate segments 226. A side wall of the first through-slot 22 is the first plate segment 224. The third plate segment 226 is opposite to the first plate segment 224. The second plate segment 225 connects the first plate segment 224 and the third plate segment 226. A bottom wall of the first through-slot 22 is the second plate segment 225. The third plate segment 226 is provided with a limiting notch 228 at an end away from the window-mounting bracket 11, and the stop portion 24 is formed on a lower side edge of the limiting notch 228. In this way, the structure is simple and easy to implement.

Of course, the stop portion 24 can also have other structural forms. For example, referring to FIG. 10 to FIG. 12, in another embodiment, a bottom wall of the first through-slot 22 is provided with a bent opening 221. A side edge of the bent opening 221 close to the window-mounting bracket 11 is folded downward to form a first flange 222. The first flange 222 is folded in a direction away from the window-mounting bracket 11 to form a second flange 223. The stop portion 24 is formed on the second flange 223. In this way, the structure is simple and easy to implement.

It can be understood that the structural form of the second limiting portion 21 has various options. For example, referring to FIG. 6 and FIG. 7, the second limiting portion 21 is configured as a limiting hole adapted to the first engaging protrusion 131. In another embodiment, the second limiting portion 21 can also be configured as a limiting notch groove adapted to the first engaging protrusion 131. Specifically, the contour of the limiting notch groove matches the first engaging protrusion 131. For example, in an embodiment where the first engaging protrusion 131 is configured as a cylinder, the limiting notch groove is configured as a cylindrical surface segment, as shown in FIG. 12. Of course, in other embodiments, a flat end surface of the first bracket 20 can also be directly used as the second limiting portion 21, without the need to additionally provide a hole structure or a notch structure.

To facilitate operation and avoid the risk of the user slipping when pushing or pulling the first bracket 20, an anti-slip portion 229 is provided on a side of the first bracket 20 away from the second limiting portion 21. The anti-slip portion 229 is configured as an anti-slip grid hole or an anti-slip grid rib.

Referring to FIG. 7, in some embodiments, the first bracket 20 is provided at an end of the load-bearing bracket 12 close to the window-mounting bracket 11. The main bracket 10 further includes a limiting bracket 14. The limiting bracket 14 is provided at an end of the load-bearing bracket 12 away from the window-mounting bracket 11, and is configured to limitingly connect the outdoor unit 102. In this way, through the joint restriction of the front and rear ends of the outdoor unit 102 by the first bracket 20 and the limiting bracket 14, the installation stability of the outdoor unit 102 can be further improved. Of course, in other embodiments, the limiting bracket 14 may also be omitted.

Referring to FIG. 1 and FIG. 9, in some embodiments, the mounting bracket assembly further includes a second bracket 30. The second bracket 30 is provided on a lower surface of the outdoor unit 102. When the outdoor unit 102 moves along the first direction on the load-bearing bracket 12, at least a portion of the limiting bracket 14 moves to above the second bracket 30 and abuts against an upper surface of the second bracket 30. In this way, the vertical restriction of the outdoor unit 102 by the limiting bracket 14 can be quickly achieved. When the user installs the outdoor unit 102, they only need to place the outdoor unit 102 on the pre-installed main bracket 10, and then push it forward to the fixed position, without requiring additional operations or auxiliary tools.

Referring to FIG. 1, FIG. 13 to FIG. 15, in some embodiments, the mounting bracket 101 further includes a support bracket 40 provided on the load-bearing bracket 12. The support bracket 40 adjusts a connection position along the first direction on the load-bearing bracket 12 to abut against an outer wall surface and/or a window sill. In this way, the support bracket 40 can adjust its installation position on the main bracket 10 along the first direction, making the position of the abutting end surface of the support bracket 40 (used for abutting against the outer wall surface and/or window sill) relative to the window-mounting bracket 11 adjustable. That is, the distance between the abutting end surface of the support bracket 40 and the window-mounting bracket 11 is adjustable. This adjustable distance can adapt to window sills of different widths. Thus, it is convenient for the user to independently adjust the installation position of the support bracket 40 on the main bracket 10, so that the support bracket 40 can properly abut against the outer wall surface and/or window sill, and the mounting bracket 101 can properly adapt to different window sill widths.

Referring to FIG. 13 to FIG. 15, in some embodiments, a lower surface of the load-bearing bracket 12 is provided with a first mounting groove 121. A plurality of limiting ribs 124 are convexly provided on a side surface of the first mounting groove 121. The plurality of limiting ribs 124 are spaced apart along the first direction, and adjacent two limiting ribs 124 form a limiting interval 125. An upper end of the support bracket 40 is provided with a third limiting portion 41. The third limiting portion 41 is provided with a second engaging protrusion 411 corresponding to the limiting interval 125. Under the elastic deformation of the third limiting portion 41, the second engaging protrusion 411 can engage with the limiting interval 125, and the second engaging protrusion 411 can be selectively installed in one of the plurality of limiting intervals 125.

In the present application, the limiting interval 125 is formed by limiting the limiting ribs 124 on the inner wall surface of the first mounting groove 121, without opening holes on the side wall of the first mounting groove 121. Therefore, it can avoid the problem of weakened structural strength of the first mounting groove 121 due to hole structures, thereby improving the structural strength of the load-bearing bracket 12, which is beneficial to the installation reliability of the outdoor unit 102. Of course, in other embodiments, a limiting hole can also be opened on a side wall or a bottom wall of the first mounting groove 121, and the first engaging protrusion 131 can engage with the limiting hole.

In some embodiments, the load-bearing bracket 12 is integrally stamped to form the limiting ribs 124. In this way, the structure is simple and easy to implement, and can reduce the manufacturing cost of the load-bearing bracket 12. Of course, in other embodiments, the limiting ribs 124 can also be separately provided from the load-bearing bracket 12, and fixed to the load-bearing bracket 12 by welding; or the load-bearing bracket 12 can be machined to form the limiting ribs 124 together with the first mounting groove 121, or the load-bearing bracket 12 can be die-cast to form the first mounting groove 121 and the limiting ribs 124.

Referring to FIG. 5, FIG. 8, FIG. 14, and FIG. 15, in some embodiments, the main bracket 10 further includes a reinforcing bracket 15. The reinforcing bracket 15 is provided on a bottom surface of the first mounting groove 121. In this way, the local structural strength of the load-bearing bracket 12 can be enhanced, which is beneficial to improving its service life and the installation reliability of the outdoor unit 102. Of course, in other embodiments, the reinforcing bracket 15 may also be omitted.

Referring to FIG. 5, FIG. 14, and FIG. 15, in some embodiments, opposite sides of the reinforcing bracket 15 are folded downward to form third flanges 151. An upper end of the support bracket 40 is provided with a sliding portion 42. An upper end of the sliding portion 42 slidingly abuts between the two third flanges 151. In this way, the reinforcing bracket 15 also serves to restrict the movement of the support bracket 40 in the left-right direction. That is, the support bracket 40 slides smoothly along the first direction (i.e., the front-rear direction) on the first mounting groove 121 without left-right shaking. Of course, in other embodiments, the reinforcing bracket 15 may not be provided with the third flanges 151, and only serves to reinforce the load-bearing bracket 12.

Referring to FIG. 5 and FIG. 15, in some embodiments, opposite sides of the reinforcing bracket 15 are further folded downward to form fourth flanges 152. The fourth flanges 152 abut against a side surface of the first mounting groove 121 and are located above the limiting ribs 124. In this way, through the fourth flanges 152, the reinforcing bracket 15 can be conveniently positioned within the first mounting groove 121, achieving better installation and fixation between the two. Of course, in other embodiments, the fourth flanges 152 may also be omitted.

Referring to FIG. 5 and FIG. 15, in some embodiments, both sides of a slot opening of the first mounting groove 121 are folded inward to form fifth flanges 121a. A lower end of the sliding portion 42 slidingly abuts between the two fifth flanges 121a. A side surface of the sliding portion 42 is convexly provided with a limiting protrusion, which slidingly abuts against an inner side surface of the fifth flanges 121a. In this way, through the simultaneous restriction of the upper and lower ends of the sliding portion 42 by the third flanges 151 and the fifth flanges 121a, the risk of left-right shaking of the load-bearing bracket 12 can be further avoided. Of course, in other embodiments, the fifth flanges 121a may also be omitted.

Referring to FIG. 14 and FIG. 15, in some embodiments, the support bracket 40 further includes a pin shaft 421. The sliding portion 42 is provided with a pin hole corresponding to the pin shaft 421. A portion of the pin shaft 421 protruding out of the pin hole is configured as the limiting protrusion. In this way, the structure is simple and easy to implement, and facilitates the assembly between the support bracket 40 and the load-bearing bracket 12. Of course, in other embodiments, the limiting protrusion can also be a protruding column welded and fixed to an outer side surface of the sliding portion 42.

Referring to FIG. 14 and FIG. 15, in some embodiments, the support bracket 40 is provided with a second mounting groove 43 and a second through-hole 44 communicating with the second mounting groove 43 and corresponding to the limiting interval 125. The third limiting portion 41 is disposed in the second mounting groove 43, and the second engaging protrusion 411 at least partially protrudes out of the second through-hole 44. In this way, the third limiting portion 41 can elastically deform smoothly and stably within the second mounting groove 43, and the second through-hole provides positioning and guiding for the second engaging protrusion 411, thereby enabling the second engaging protrusion 411 to more stably engage into or disengage from the limiting interval 125. Of course, in other embodiments, the second mounting groove 43 and the second through-hole 44 may also be omitted, and the support bracket 40 can directly form the third limiting portion 41 and the second engaging protrusion 411.

Referring to FIG. 14, in some embodiments, both side surfaces of the first mounting groove 121 are provided with limiting ribs 124. Two second engaging protrusions 411 and two second through-holes 44 are correspondingly provided, and the two second engaging protrusions 411 are installed in one-to-one correspondence with the two side surfaces of the first mounting groove 121. In this way, both left and right sides of the support bracket 40 are subjected to forces applied by the second mounting groove 43, which can improve the sliding smoothness and installation stability of the support bracket 40. Of course, in other embodiments, only one side of the limiting rib and the second engaging protrusion 411 may be provided.

Referring to FIG. 14 and FIG. 15, in some embodiments, a bottom wall of the second mounting groove 43 is provided with a folded opening 45. A side edge of the folded opening 45 close to the load-bearing bracket 12 is folded toward a slot opening of the second mounting groove 43 to form a sixth flange 46. The sixth flange 46 is folded downward to form a seventh flange 47. The side edge of the folded opening 45, the sixth flange 46, and the seventh flange 47 jointly define an installation space. The third limiting portion 41 includes two intersecting third segments 412. First ends of the two third segments 412 are connected and disposed in the installation space. Second ends of the third segments 412 are provided with the second engaging protrusion 411. In this way, the sixth flange 46 and the seventh flange 47 can position and restrict the third limiting portion 41, enabling the third limiting portion 41 to be stably installed within the second mounting groove 43 and to elastically deform smoothly within the second mounting groove 43. Of course, in other embodiments, the sixth flange 46 and the seventh flange 47 may also be omitted.

Referring to FIG. 16 to FIG. 24, in another embodiment of the present application, the mounting bracket assembly includes: a mounting bracket 101 and a first bracket 20.

The mounting bracket 101 includes a main bracket 10. The main bracket 10 includes a window-mounting bracket 11 and a load-bearing bracket 12 connected to each other, the window-mounting bracket 11 is mounted on a window frame, the load-bearing bracket 12 extends along a first direction to the outside of a window 103, and an outdoor unit 102 is provided on an upper surface of the load-bearing bracket 12.

The first bracket 20 is connected to the outdoor unit 102, one of the load-bearing bracket 12 and the first bracket 20 is provided with a first limiting portion 13 capable of elastic deformation, and the other of the load-bearing bracket 12 and the first bracket 20 is provided with a second limiting portion 21. During the process of the outdoor unit 102 moving relative to the load-bearing bracket 12 to an installation position, the first limiting portion 13 can be elastically engaged with the second limiting portion 21.

In the technical solution of the present application, after the outdoor unit 102 is installed on the load-bearing bracket 12 and is at the installation position, the first limiting portion 13 can be elastically engaged with the second limiting portion 21, achieving a limiting connection with the second limiting portion 21, thereby restricting the outdoor unit 102 at the installation position, i.e., completing the installation and fixation of the outdoor unit 102. In this way, through the cooperative structure of the first limiting portion 13 and the second limiting portion 21, the installation and fixation of the outdoor unit 102 do not require screws and corresponding tools such as screwdrivers. This operation is more convenient, thereby improving the user experience.

Referring to FIG. 16 to FIG. 32, in some embodiments, optionally, the first limiting portion 13 is provided on the load-bearing bracket 12, and the second limiting portion 21 is provided on the first bracket 20. During the process of the outdoor unit 102 being placed on the load-bearing bracket 12 from top to bottom and reaching the installation position, the first bracket 20 can urge the first limiting portion 13 to elastically deform in a direction intersecting with a vertical direction, so as to be elastically engaged with the second limiting portion 21.

Specifically, in the embodiment of the present application, the inner side of the window 103 is defined as the rear, and the outer side of the window 103 is defined as the front. Thus, the front-rear direction is the first direction, the upper side of the outdoor unit 102 is the upper side, and the lower side of the outdoor unit 102 is the lower side. When facing forward, the left side of the outdoor unit 102 is the left side, and the right side of the outdoor unit 102 is the right side.

In the present application, during the process of the outdoor unit 102 being placed on the load-bearing bracket 12 from top to bottom, the first bracket 20 extending along the vertical direction can push against the first limiting portion 13, causing the first limiting portion 13 to elastically deform in a direction intersecting with the vertical direction. That is, the first limiting portion 13 elastically deforms in a substantially horizontal plane. When the first bracket 20 falls to a preset position following the outdoor unit 102 (i.e., when the outdoor unit 102 is at the installation position), the elastic potential energy of the first limiting portion 13 decreases and it engages with the second limiting portion 21, thereby completing the restriction of the first bracket 20 by the load-bearing bracket 12. In this way, only this single installation operation of placing from top to bottom is required to complete the drop-in fixation of the outdoor unit 102 on the mounting bracket 101. The operation is more convenient, thereby further improving the user experience.

Of course, in other embodiments, the first limiting portion 13 can also be provided on the first bracket 20, and the second limiting portion 21 can be provided on the load-bearing bracket 12. In this case, the first limiting portion 13 can fall to a preset position following the outdoor unit 102, while the second limiting portion 21 remains in its original position. During the falling process, the first limiting portion 13 will be urged by the first bracket 20 to elastically deform, and finally engage with the second limiting portion 21, thereby completing the restriction of the first bracket 20 by the load-bearing bracket 12.

It should be noted that the installation method of the outdoor unit 102 is not limited to the aforementioned direct drop-in scheme from top to bottom. In other embodiments, the outdoor unit 102 is first placed on the load-bearing bracket 12 from top to bottom, and then the outdoor unit 102 is pushed or pulled to enable it to move along the first direction on the load-bearing bracket 12 to the installation position. At this time, the first limiting portion 13 elastically deforms and restricts the second limiting portion 21. That is, in the present application, two installation operations are required to place the outdoor unit 102 at the installation position.

Specifically and optionally, the outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 close to the window, and then pushed forward to the installation position. That is, after being pushed in a direction away from the window to the installation position, the first limiting portion 13 can limitingly connect the second limiting portion 21. Alternatively, the outdoor unit 102 is first placed from top to bottom on the end of the load-bearing bracket 12 away from the window, and then pulled backward to the installation position. That is, after being pulled in a direction close to the window to the installation position, the first limiting portion 13 can limitingly connect the second limiting portion 21.

Referring to FIGS. 20, 26, 29, and 32, in some embodiments, the first bracket 20 includes a pin 25 extending along the vertical direction, and the second limiting portion 21 is provided on a side surface of the pin 25. In this way, the structure is simple and easy to implement. Of course, in other embodiments, such as in an embodiment where the outdoor unit 102 is first placed from top to bottom and then moved along the first direction to the installation position, the first bracket 20 can also extend along the front-rear direction, and the first bracket 20 is not limited to the pin form. For example, the first bracket 20 can be configured as a tubular structure.

In some embodiments, a lower end surface of the pin 25 is provided with a guide surface 212. An axial cross-sectional diameter of the guide surface 212 is gradually reduced in a top-to-bottom direction, and the second limiting portion 21 is disposed above the guide surface 212. It should be noted that the axial cross-section of the guide surface 212 refers to the cross-section obtained by cutting it with a plane perpendicular to the axis of the pin 25. In this way, the guide surface 212 can provide a good guiding action, enabling the pin 25 to more smoothly contact and push against the first limiting portion 13. Of course, in other embodiments, the guide surface 212 may also be omitted, or the guide surface 212 can be provided on the first limiting portion 13.

In some embodiments, the second limiting portion 21 is a stop groove provided on the side surface of the pin 25. In this way, both the upper side surface and the lower side surface of the stop groove can restrict the first limiting portion 13, thereby improving the connection reliability between the first limiting portion 13 and the first bracket 20. In other embodiments, the second limiting portion 21 can also be a stop step convexly provided on a side surface of the first bracket 20, and the first limiting portion 13 can engage with an upper surface of the stop step.

Referring to FIGS. 20, 21, 26, 29, and 32, in some embodiments, the mounting bracket assembly further includes a mounting base 80 provided on the load-bearing bracket 12. The mounting base 80 includes a guide tube portion 81. The guide tube portion 81 is provided with a tube inner cavity 811 for the pin 25 to be inserted into, and a clearance opening 812 communicating with a side surface of the tube inner cavity 811. The first limiting portion 13 includes an engaging portion 31. The engaging portion 31 is capable of being inserted into the tube inner cavity 811 from the clearance opening 812 and engaging with the second limiting portion 21. In this way, the guide tube portion 81 can guide and limit the pin 25, which is not only beneficial for the pin 25 to smoothly insert into the tube inner cavity 811, but also can prevent the first bracket 20 from shaking front-back or left-right on the load-bearing bracket 12. Of course, in other embodiments, the mounting base 80 may also be omitted. For example, the load-bearing bracket 12 is provided with a pin hole corresponding to the pin 25, the first limiting portion 13 is provided on a lower surface of the load-bearing bracket 12, and a portion of the pin 25 passing through the pin hole is provided with the second limiting portion 21.

Referring to FIGS. 16, 17, 25, 27, 28, 30, and 31, in some embodiments, in an embodiment where the outdoor unit 102 can be placed on the load-bearing bracket 12 from top to bottom and reach the installation position, the mounting bracket assembly further includes a second bracket 72 provided on an end of the outdoor unit 102 away from the window-mounting bracket 11. The second bracket 72 includes a pin shaft extending along the vertical direction, and the main bracket 10 is provided with a pin hole 141 for the pin shaft to be adaptively inserted. In this way, during the process of the outdoor unit 102 being drop-installed on the load-bearing bracket 12 from top to bottom, the cooperation between the pin shaft and the pin hole 141 can provide a guiding action, so that the pin 25 can more easily align with the tube inner cavity 811, thereby facilitating the drop-in operation. Of course, in other embodiments, the second bracket 72 may also be omitted.

Referring to FIGS. 16, 17, 25, 27, 28, 30, and 31, in some embodiments, the main bracket 10 further includes a limiting bracket 14. The limiting bracket 14 is provided at an end of the load-bearing bracket 12 away from the window-mounting bracket 11, and at least partially protrudes from an upper surface of the load-bearing bracket 12. In this way, the portion of the limiting bracket 14 protruding from the upper surface of the load-bearing bracket 12 can restrict a front side surface of the outdoor unit 102, preventing the outdoor unit 102 from moving excessively forward and falling out of the load-bearing bracket 12. Of course, in other embodiments, the limiting bracket 14 may also be omitted.

In some embodiments, two load-bearing brackets 12 and two first limiting portions 13 are provided and installed in one-to-one correspondence. The two load-bearing brackets 12 are respectively provided at opposite ends of the limiting bracket 14. The pin hole 141 is disposed in a middle portion of the limiting bracket 14, and the second bracket 72 is convexly provided on a lower surface of the outdoor unit 102. In this way, the pin hole 141 located on the limiting bracket 14 and the two guide tube portions 81 located on the load-bearing brackets 12 jointly form a triangular positioning arrangement, which can better restrict the outdoor unit 102, thereby improving the installation reliability of the outdoor unit 102. In other embodiments, the pin hole 141 can also be provided on the load-bearing bracket 12. For example, the pin shaft is provided at an end of the load-bearing bracket 12 away from the window-mounting bracket 11, and both the pin shaft and the pin hole 141 are provided in pairs, corresponding one-to-one with the two load-bearing brackets 12.

Referring to FIGS. 16 to 21, 30 to 32, in some embodiments, the first limiting portion 13 further includes a fixing portion 32 connected to the engaging portion 31. The mounting base 80 further includes a mounting plate 82 connected to the guide tube portion 81. The fixing portion 32 is clamped between the mounting plate 82 and the load-bearing bracket 12. In this way, by pressing the fixing portion 32 against the load-bearing bracket 12 through the mounting plate 82, the fixing portion 32 is fixed relative to the load-bearing bracket 12. The structure is simple and easy to implement. Specifically and optionally, the mounting plate 82 is locked to the load-bearing bracket 12 by screws. Of course, in other embodiments, the mounting plate 82 can also be fixed to the load-bearing bracket 12 by riveting, welding, or bonding.

Referring to FIGS. 16 to 21, 30 to 32, in some embodiments, a lower surface of the mounting plate 82 is provided with an accommodating groove 821. A bottom of the accommodating groove 821 is provided with an annular stop rib 822. The fixing portion 32 is suitably sleeved on an outer peripheral surface of the annular stop rib 822, and is clamped between a bottom surface of the accommodating groove 821 and an upper surface of the load-bearing bracket 12. In this way, through the mutual restriction of the annular stop rib 822 and the fixing portion 32, and utilizing the clamping force jointly applied by the mounting plate 82 and the load-bearing bracket 12, the fixing portion 32 can be reliably restricted within the accommodating groove 821, which is beneficial to the displacement stability of the engaging portion 31. Of course, in other embodiments, the accommodating groove 821 and the annular stop rib 822 may also be omitted. The fixing portion 32 can be directly fixed to a lower surface of the mounting plate 82 by welding, riveting, or bonding, and then the mounting plate 82 is fixed to the load-bearing bracket 12.

It should be noted that the annular structure in the present application, such as the annular stop rib 822, does not specifically refer to a complete circular ring structure, but includes non-complete circular ring structures. That is, it includes embodiments where the annular stop rib 822 is broken at one point to form two opposite ends, as shown in FIG. 6 and FIG. 17. For example, a plurality of stop ribs spaced apart along the circumferential direction of the pin 25, where the plurality of stop ribs jointly form a substantially complete annular structure.

Referring to FIGS. 16 to 20, 25, and 26, in some embodiments, the first bracket 20 further includes a bridge bracket 26. The bridge bracket 26 is provided on a side of the outdoor unit 102 close to the window-mounting bracket 11. The pin 25 is provided on a lower side surface of the bridge bracket 26. In this way, the cooperative structure of the first limiting portion 13 and the first bracket 20 can be exposed behind the outdoor unit 102, facilitating the user to observe and operate the first limiting portion 13, and providing a larger operating space, thereby improving the user experience. Of course, in other embodiments, the first bracket 20 can also be provided on a lower surface of the outdoor unit 102, such as the structures shown in the third and fourth embodiments.

Referring to FIGS. 17, 19, and 25, in some embodiments, the bridge bracket 26 is provided with a mounting through-hole 261. The outdoor unit 102 is provided with a threaded hole. The mounting bracket assembly further includes a hand-tightening bolt 71. The mounting through-hole 261 is installed on the threaded hole through the hand-tightening bolt 71. In this way, it is convenient for the user to independently assemble and disassemble the bridge bracket 26, providing another operation method for assembling and disassembling the outdoor unit 102 for the user to choose, thereby improving the flexibility and convenience of assembling and disassembling the outdoor unit 102. Specifically, in addition to the operation method of installing or disassembling the bridge bracket 26 and the outdoor unit 102 together, the user can also, during the installation operation, first place the outdoor unit 102 alone onto the load-bearing bracket 12, then align the pin 25 on the bridge bracket 26 with the guide tube portion 81 of the mounting base 80. After the pin 25 is inserted into the guide tube portion 81, the mounting through-hole 261 of the bridge bracket 26 can align with the threaded hole. Finally, the hand-tightening bolt 71 is used to lock the mounting through-hole 261 and the threaded hole together. Similarly, during the disassembly operation, first release the connection between the mounting through-hole 261 and the threaded hole by the hand-tightening bolt 71, then remove the pin 25 and the bridge bracket 26, and finally lift the outdoor unit 102 alone away from the load-bearing bracket 12.

Referring to FIGS. 18, 20, and 21, in an embodiment, an upper surface of the mounting plate 82 is convexly provided with a first stop protrusion 129. When the engaging portion 31 is engaged with the second limiting portion 21, the first stop protrusion 129 is located on a side of the engaging portion 31 away from the second limiting portion 21. The first limiting portion 13 is capable of elastic deformation to enable the engaging portion 31 to be engaged on a side of the first stop protrusion 129 away from the second limiting portion 21. In this way, through the first stop protrusion 129, the engaging portion 31 can be restricted in a released state disengaged from the second limiting portion 21, so that the user can more easily lift the outdoor unit 102 away from the load-bearing bracket 12 and complete the disassembly of the outdoor unit 102. Of course, in other embodiments, the first stop protrusion 129 may also be omitted. The user can toggle the first limiting portion 13 to disengage the engaging portion 31 from the second limiting portion 21 while simultaneously lifting the outdoor unit 102, which can also achieve the disassembly of the outdoor unit 102.

Referring to FIGS. 18, 20, and 21, in an embodiment, the first limiting portion 13 further includes an operating portion 33 connected to the fixing portion 32. The operating portion 33 is exposed above the load-bearing bracket 12 and is configured for applying an operating force. In this way, the operating portion 33 can facilitate the user to toggle the first limiting portion 13 to engage the engaging portion 31 with the first stop protrusion 129. Specifically and optionally, the operating portion 33 includes two intersecting straight rod segments. A first straight rod segment is arranged opposite to the engaging portion 31, and a second straight rod segment connects the first straight rod segment and the engaging portion 31. Of course, in other embodiments, the operating portion 33 can also be configured as a pull ring, or the operating portion 33 may be omitted.

Referring to FIG. 25 and FIG. 26, in an embodiment, the first limiting portion 13 further includes a fixing portion 32 intersecting with the engaging portion 31. The load-bearing bracket 12 is provided with a mounting portion 126 corresponding to the fixing portion 32. The fixing portion 32 is connected to the mounting portion 126. In this way, the load-bearing bracket 12 is directly provided with the mounting portion 126 for installing the first limiting portion 13, which can simplify the structure of the mounting bracket assembly.

It should be noted that the first stop protrusion 129 is not limited to being provided on the mounting base 80, and can also be provided on the load-bearing bracket 12. For example, referring to FIG. 25 and FIG. 26, in an embodiment, the mounting portion 126 is provided on an upper surface of the load-bearing bracket 12. The upper surface of the load-bearing bracket 12 is further provided with a first stop protrusion 129. When the engaging portion 31 is engaged with the second limiting portion 21, the first stop protrusion 129 is located on a side of the engaging portion 31 away from the second limiting portion 21. The first limiting portion 13 is capable of elastic deformation to enable the engaging portion 31 to be engaged on a side of the first stop protrusion 129 away from the second limiting portion 21. In this way, through the first stop protrusion 129, the engaging portion 31 can be restricted in a released state disengaged from the second limiting portion 21, so that the user can more easily lift the outdoor unit 102 away from the load-bearing bracket 12 and complete the disassembly of the outdoor unit 102.

Referring to FIG. 25 and FIG. 26, in an embodiment, optionally, an upper surface of the load-bearing bracket 12 is further provided with a second stop protrusion 130. The second stop protrusion 130 is provided on a side of the engaging portion 31 close to the second limiting portion 21, and the engaging portion 31 abuts against the second stop protrusion 130. In this way, the second stop protrusion 130 can prevent the engaging portion 31 of the first limiting portion 13 from excessively inserting into the tube inner cavity 811, which is beneficial to the insertion of the pin 25 into the tube inner cavity 811. Further optionally, the second stop protrusion 130 is provided at an end of the engaging portion 31 close to the fixing portion 32. That is, the second stop protrusion 130 is disposed close to a rotation axis of the engaging portion 31. Of course, in other embodiments, the second stop protrusion 130 may also be omitted.

In an embodiment, the mounting portion 126 is provided on a side of the engaging portion 31 away from the second stop protrusion 130, and includes two installation protruding ribs spaced apart and opposite to each other. The installation protruding ribs are provided with insertion holes, and the fixing portion 32 can be inserted into the two insertion holes. In this way, the structure is simple and facilitates the installation and fixation of the fixing portion 32. Of course, in other embodiments, the mounting portion 126 can also adopt other structural forms, such as an annular protruding rib, where the fixing portion 32 is suitably sleeved on an outer peripheral surface of the annular protruding rib. The present application does not specifically limit this.

In an embodiment, the load-bearing bracket 12 integrally forms the first stop protrusion 129, the second stop protrusion 130, and the installation protruding ribs by stamping. In this way, the production steps of the structure of the load-bearing bracket 12 can be simplified, thereby reducing the manufacturing cost of the load-bearing bracket 12. Of course, in other embodiments, the first stop protrusion 129, the second stop protrusion 130, and the installation protruding ribs can also be separately provided from the load-bearing bracket 12, and fixed to the load-bearing bracket 12 by welding or screwing.

Referring to FIG. 27 to FIG. 29, in an embodiment, the second limiting portion 21 extends along a circumferential direction of the pin 25. The first limiting portion 13 includes a first rod segment 30a and a second rod segment 30b connected to each other. The first rod segment 30a is sleeved on a circumferential side surface of the guide tube portion 81. The second rod segment 30b extends into the tube inner cavity 811 and is configured as the engaging portion 31. In this way, through the elastic deformation of the first rod segment 30a on the guide tube portion 81, the second rod segment 30b can be urged to engage with or disengage from the second limiting portion 21. The structure is simple and easy to implement.

Referring to FIG. 27 to FIG. 29, in an embodiment, the first limiting portion 13 further includes a third rod segment 30c connected to the second rod segment 30b. The third rod segment 30c extends from the second rod segment 30b in a direction away from the second limiting portion 21, and is at least partially exposed to a side of the load-bearing bracket 12 for being toggled. In this way, the portion of the third rod segment 30c exposed to the side of the load-bearing bracket 12 can be toggled by the user to urge the first rod segment 30a and the second rod segment 30b to elastically deform, thereby releasing the engagement of the second rod segment 30b with the second limiting portion 21. The operating space is large and the operation is labor-saving, thereby improving the user experience. Of course, in other embodiments, the third rod segment 30c may also be omitted.

In an embodiment, a central axis of the second rod segment 30b extends along an arc. The second rod segment 30b is formed with an anti-detachment recess 34 on a side away from the second limiting portion 21. The mounting base 80 is provided with an anti-detachment protruding column 825 corresponding to the anti-detachment recess 34. The anti-detachment protruding column 825 is provided on a side of the anti-detachment recess 34 away from the second limiting portion 21. In this way, the anti-detachment protruding column 825 can prevent the first rod segment 30a from excessively deforming and detaching from the guide tube portion 81, thereby improving the operational stability of the first limiting portion 13. Of course, in other embodiments, the anti-detachment protruding column 825 may also be omitted. Furthermore, the central axis of the second rod segment 30b can also extend along a bent multi-segment straight line, or along an S-shaped curve, etc.

Referring to FIG. 29, in an embodiment, the mounting base 80 further includes a mounting plate 82 connected to a side surface of the guide tube portion 81. At least two anti-detachment engaging protrusions 813 are convexly provided on a circumferential side surface of the guide tube portion 81. The at least two anti-detachment engaging protrusions 813 are spaced apart along the circumferential direction of the guide tube portion 81. The anti-detachment engaging protrusions 813 and a lower surface of the mounting plate 82 jointly define an anti-detachment annular groove. The first rod segment 30a is embedded in the anti-detachment annular groove. In this way, the first rod segment 30a can stably deform on the guide tube portion 81, preventing the first rod segment 30a from detaching from the guide tube portion 81, which would cause the second rod segment 30b to be unable to insert into the tube inner cavity 811. This improves the reliability of state switching between engagement and disengagement of the engaging portion 31 with the second limiting portion 21. Of course, in other embodiments, the anti-detachment engaging protrusions 813 may also be omitted, and an anti-detachment annular groove can be directly opened on the circumferential side surface of the guide tube portion 81.

Referring to FIG. 28 and FIG. 29, in an embodiment, a lower side surface of the load-bearing bracket 12 is provided with a first mounting groove 121. The mounting plate 82 is disposed in the first mounting groove 121. A bottom of the first mounting groove 121 is provided with a first through-hole 122. The guide tube portion 81 is inserted into the first through-hole 122. A slot side of the first mounting groove 121 is provided with a clearance opening 128. One end of the third rod segment 30c passes out of the clearance opening 128 and can swing along an extension direction of the clearance opening 128. In this way, the structural form of the first mounting groove 121 can improve the structural strength of the load-bearing bracket 12, and can hide most of the structures of the mounting base 80 and the first limiting portion 13 within the first mounting groove 121. This not only provides protection for them but also improves the neatness and aesthetics of the air conditioner. Of course, in other embodiments, the load-bearing bracket 12 may also not be provided with the first mounting groove 121.

Referring to FIG. 29, in an embodiment, an end of the third rod segment 30c passing out of the clearance opening 128 is provided with an operating portion 33. The operating portion 33 is configured for applying an operating force. In this way, the operating portion 33 can facilitate the user to toggle the first limiting portion 13 to disengage the engaging portion 31 from the second limiting portion 21. Specifically and optionally, the operating portion 33 is configured as a pull ring structure. Of course, in other embodiments, the operating portion 33 can also include two intersecting straight rod segments. A first straight rod segment is arranged opposite to the engaging portion 31, and a second straight rod segment connects the first straight rod segment and the engaging portion 31. Of course, the operating portion 33 may also be omitted.

Referring to FIG 30 to FIG. 32, in an embodiment, the first limiting portion 13 further includes an operating portion 33 connected to the engaging portion 31 and the fixing portion 32. The load-bearing bracket 12 is provided with a second through-hole 123 corresponding to the operating portion 33. The operating portion 33 passes through the second through-hole 123 and is exposed below the load-bearing bracket 12. The operating portion 33 is drivable to deform along an extension direction of the second through-hole 123, so as to engage or disengage the engaging portion 31 with/from the second limiting portion 21. In this way, through the guiding and limiting action of the second through-hole 123 on the operating portion 33, when the user applies an operating force to the operating portion 33, the engaging portion 31 can timely and effectively disengage from the second limiting portion 21.

Referring to FIG. 30 to FIG. 32, in an embodiment, a bottom of the first mounting groove 121 is provided with a first through-hole 122 corresponding to the guide tube portion 81. The guide tube portion 81 is disposed in the first through-hole 122, and the clearance opening 812, the engaging portion 31, and the fixing portion 32 are all provided on an upper surface of the load-bearing bracket 12. In this way, it is convenient for the user to observe whether the engaging portion 31 and the second limiting portion 21 are engaged in place. Further optionally, the second through-hole 123 communicates with the first through-hole 122, facilitating the processing of the first through-hole 122 and the second through-hole 123 on the load-bearing bracket 12. Of course, in other embodiments, the first through-hole 122 and the second through-hole 123 can also be separated, or the clearance opening 812, the engaging portion 31, and the fixing portion 32 can be provided on a lower surface of the load-bearing bracket 12.

Referring to FIGS. 16, 17, 19, 20, 23 to 25, 27, 28, 30, and 31, in some embodiments, the mounting bracket 101 further includes a support bracket 40 provided on the load-bearing bracket 12. The support bracket 40 is adjustably connected in position along the first direction on the load-bearing bracket 12, and abuts against an outer wall surface and/or a window sill. In this way, the support bracket 40 can adjust its installation position on the main bracket 10 along the first direction, making the position of the abutting end surface of the support bracket 40 (used for abutting against the outer wall surface and/or window sill) relative to the window-mounting bracket 11 adjustable. That is, the distance between the abutting end surface of the support bracket 40 and the window-mounting bracket 11 is adjustable. This adjustable distance can adapt to window sills of different widths. Thus, it is convenient for the user to independently adjust the installation position of the support bracket 40 on the main bracket 10, so that the support bracket 40 can properly abut against the outer wall surface and/or window sill, and the mounting bracket 101 can properly adapt to different window sill widths. Of course, in other embodiments, the support bracket 40 can also be fixedly disposed below the load-bearing bracket 12.

Referring to FIGS. 20, 23, 24, and 32, in some embodiments, a lower surface of the load-bearing bracket 12 is provided with a first mounting groove 121. The main bracket 10 further includes a reinforcing bracket 60. The reinforcing bracket 60 is provided on a bottom surface of the first mounting groove 121. In this way, the local structural strength of the load-bearing bracket 12 can be enhanced, which is beneficial to improving its service life and the installation reliability of the outdoor unit 102. Of course, in other embodiments, the reinforcing bracket 60 may also be omitted.

In some embodiments, opposite sides of the reinforcing bracket 60 are folded downward to form first flanges 61. The first flanges 61 are provided with serrated portions 62 extending along the first direction. The support bracket 40 slidingly abuts against the serrated portions 62 when moving along the first direction. In this way, through the serrated portions 62 providing support force and resistance to the support bracket 40, the support bracket 40 can both move along the first direction under a relatively large external force and stably support between the load-bearing bracket 12 and the outer wall surface.

Of course, in other embodiments, the mounting bracket 101 can also include an embedded bracket. The embedded bracket includes an embedded portion provided on an upper end of the support bracket 40. The embedded portion includes two opposite first plate portions and a second plate portion connecting the two first plate portions. The embedded portion is adaptively embedded in the first mounting groove 121. Specifically, the first plate portions and the second plate portion are interference-fitted with the first mounting groove 121. Both the first plate portions and the second plate portion abut against an inner surface and/or a slot opening side edge of the first mounting groove 121. The static friction generated by the tight fit can achieve relative fixation of the upper end of the support bracket 40 within the first mounting groove 121. When it is necessary to adjust the installation position of the support bracket 40 along the first direction within the first mounting groove 121, a tool such as a hammer can be used to strike the support bracket 40. In this way, the structure of the mounting bracket 101 can be simplified. Furthermore, through the additionally provided embedded bracket, the contact area between the embedded portion and the first mounting groove 121 can be increased, thereby increasing the friction between the two, and reducing the risk of the support bracket 40 moving along the first direction on its own.

Referring to FIGS. 20, 23, and 24, in an embodiment, the serrated portion 62 is provided on a lower surface of the first flange 61, and an upper end surface of the support bracket 40 abuts against the serrated portion 62. In this way, the structure is simple and easy to implement. Further optionally, both sides of a slot opening of the first mounting groove 121 are folded inward to form second flanges 127. Opposite sides of the support bracket 40 are convexly provided with sliding portions 53 and limiting protrusions 54. The two sliding portions 53 slidingly abut between the two second flanges 127, and the limiting protrusions 54 slidingly abut against upper side surfaces of the second flanges 127. In this way, the installation stability of the support bracket 40 on the load-bearing bracket 12 can be improved. Of course, in other embodiments, the second flanges 127 may also be omitted.

Referring to FIG. 32, in another embodiment, the first flange 61 is provided with a guide channel 63 extending along the first direction. A lower side surface of the guide channel 63 is provided with a serrated portion 62. An outer side surface of the support bracket 40 is provided with a limiting protrusion 54 corresponding to the serrated portion 62. The limiting protrusion 54 is adaptively installed on the serrated portion 62.

In another embodiment, both sides of a slot opening of the first mounting groove 121 are folded inward to form second flanges 127. A lower side surface of the first flange 61 abuts against an upper side surface of the second flanges 127. Opposite sides of the support bracket 40 are convexly provided with sliding portions 53 and limiting protrusions 54. The two sliding portions 53 slidingly abut between the two first flanges 61. In this way, the installation stability of the support bracket 40 on the load-bearing bracket 12 can be improved. Of course, in other embodiments, the second flanges 127 may also be omitted.

Referring to FIGS. 20, 24, and 32, in some embodiments, a side of the support bracket 40 facing the window-mounting bracket 11 is provided with a second mounting groove 51. The support bracket 40 further includes a limiting shaft 52 passing through two side walls of the second mounting groove 51. A portion of the limiting shaft 52 protruding out of the second mounting groove 51 is configured as the limiting protrusion 54. In this way, the structure is simple and easy to implement, and facilitates the assembly between the support bracket 40 and the load-bearing bracket 12. Of course, in other embodiments, the limiting protrusion 54 can also be a protruding column welded and fixed to an outer side surface of the sliding portion 53.

The present application further proposes an air conditioner, including an outdoor unit and the aforementioned mounting bracket assembly. For the specific structure of the mounting bracket assembly, reference is made to the above embodiments. Since the present air conditioner adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
